Description
Technical field
The utility model relates to a kind of novel Portunus trituberculatus Miers grow seedlings net cage and affiliated facility, belongs to aquaculture field.
Background technology
Portunus trituberculatus Miers is traditional famous and precious marine product, its delicious meat, unique flavor, is of high nutritive value, and not only is subjected to domestic coastal and landlocked consumer's favor deeply, also finds a good sale in international markets such as Japan, Korea S, America and Europe, is China's important export foreign-exchange-earning export products.In recent ten years, along with the continuous increase of the reducing year by year of marine fishing output, domestic and international market demand, swimming crab is propagated maritime provinces such as Liaoning in China, Shandong, Jiangsu, Zhejiang, Fujian, Guangdong, Guangxi artificially and rises rapidly.Since 2000, because the swimming crab cultured area enlarges, demand increases severely, and wild seed can not be satisfied the breed demand, various places are carried out Portunus trituberculatus Miers industrial artificial seedling rearing or seedling rearing in earth ponds one after another, for alleviating in short supply the playing an important role of China swimming crab seed.
Factorial seedling growth is to carry out in indoor cement pit, controls the incubation temperature of swimming crab artificially, the reproductive output height, but the seedling that temperature control brings out adaptive capacity to environment is poor to external world, it is low that seed is cultured in the commodity crab process survival rate; And seedling rearing in earth ponds is good to the adaptability of environment, the survival rate height, but need a large amount of water surface resources, in addition, output is relatively low.Chinese invention patent CN100403885C provides a kind of propagation method of Portunus trituberculatus Miers, but this method is still in cistern and carries out.Therefore be necessary very much to design a kind of, both solved the adaptability problem of the young natural surroundings at outdoor culture facility, simultaneously again can be with the indoor raising of seedling production that equally intensifies.
Summary of the invention
The utility model mainly is the technical problem at existing in prior technology etc., a kind of grow seedlings net cage and affiliated facility that is applicable to the breeding of Portunus trituberculatus Miers outdoor ponds is provided, solved the problem of the needs that in the larval culture process natural surroundings adapted to, improved its survival rate, accomplish that simultaneously seedling-growing time is concentrated relatively, be convenient to the cultivation of the young.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals:
A kind of Portunus trituberculatus Miers grow seedlings net cage and affiliated facility is characterized in that: comprise that close crab supports cage, hatching net cage and young adherance temporarily, it is the cage shape cylindrical shell that is made of skeleton and net sheet that close crab is supported cage temporarily, and its top is provided with the bait throwing in mouth, and the bottom is provided with sinker; The hatching net cage comprises net cage support and casing, and the upper and lower opening of net cage body is equipped with the guiding principle rope, is separately fixed at the upper and lower of net cage support, and the hatching net cage is made by the net sheet; Young adherance is netted lamellar structure, and its top is provided with float, and the bottom is provided with net and weighs down; Young adherance and close crab are supported the inside that cage is fixed on the hatching net cage temporarily.
Portunus trituberculatus Miers is positioned over close crab and supports ectogenesis in the cage temporarily, the young that hatches can be distributed in hatching net cage inside, then attached to growing on the young adherance, has realized Portunus trituberculatus Miers the breeding naturally of outdoor net cage, thereby has simplified manual operation.
As preferably, guiding principle rope suitable for reading is provided with crossbeam, and close crab is supported cage temporarily and is fixed on the crossbeam by hoist cable.The close crab that this structure is supported in the cage close crab is temporarily arranged seedling, cloth children conveniently in the hatching net cage.
As preferably, the net cage support is provided with four, is to be made by mao bamboon.Mao bamboon is easily fixing and not perishable in water.
As preferably, it is nontoxic polythene net sheet that close crab is supported cage net sheet, net cage net sheet and young adherance temporarily.The polythene net sheet helps adhering to of juvenile crab and grows.
As preferably, parallel equidistant is arranged between a plurality of young adherances.Each hatching net cage is established close crab and is supported 2 in cage temporarily, and between net cage inboard and young adherance.
The utility model is provided with the net cage breeding in coastal beach pond, oogenesis parent crab is supported in the cage temporarily and cultivates, cloth seedling in the hatching net cage, the young is cultivated in net cage, and these facilities are all in same pond, easy to operate, simultaneously owing to be to carry out in outdoor coastal beach pond, the swimming crab seed that the brings out adaptability of environment to external world is good, the survival rate height, to emerge neat, overcome juvenile crab that the greenhouse the brings out shortcoming of environmental suitability difference to external world.In addition, the quantity of net cage setting can determine that net cage seedling nursery is very convenient flexibly according to what, the size of breeding scale of close crab, and it both had been suitable for raiser's small-scale production, also being suitable for extensive intensification and producing.
